摘要
该文讨论了采样图象的一般模型,提出了离散图象的采样准则,给出了一种迭代算法。该算法是对传统CG算法的改进。仿真结果表明,该算法是有效的,且其收敛速度快于CG。
This paper discusses the general model of Non-uniform sampling image,and present s the sampling principle of discrete image.An iterative algorithm is given.This algorithm can improve the efficiency of the CG.Simulation result shows that this method is effective and its convergence rate is faster than CG.
